Abstract: A data processing apparatus contains branch prediction circuitry including a micro branch target buffer, a full branch target buffer and a global history buffer. The branch target buffer entries contain history data which indicates whether or not a number of the following blocks of program instructions, subsequent to and sequential to a block of program instruction identified by that branch target buffer entry containing a branch instruction, do themselves contain any branch instructions. If the history data indicates that the following blocks of program instructions do not contain branches, then the operation of the branch prediction circuitry is suppressed for these following blocks of program instructions so as to save energy.

Abstract: A cache hierarchy and a method of operating the cache hierarchy are disclosed. The cache hierarchy comprises a first cache level comprising an instruction cache, and predecoding circuitry to perform a predecoding operation on instructions having a first encoding format retrieved from memory to generate predecoded instructions having a second encoding format for storage in the instruction cache. The cache hierarchy further comprises a second cache level comprising a cache and the first cache level instruction cache comprises cache control circuitry to control an eviction procedure for the instruction cache in which a predecoded instruction having the second encoding format which is evicted from the instruction cache is stored at the second cache level in the second encoding format. This enables the latency and power cost of the predecoding operation to be avoided when the predecoded instruction is then retrieved from the second cache level for storage in the first level instruction cache again.

Abstract: To effectively manage virtualized components, a virtual network manager aggregates components into entities and maintains an entity inventory that indicates available resources within a virtual network. However, aggregating components into entities and managing the entity inventory as components come on/offline can be computationally intensive. To reduce computation time and improve consistency, the virtual network manager uses a key service that associates components with entity keys. When a component is again instantiated within a virtual network, the virtual network manager passes an identifier for the component to the key service to retrieve an associated entity key. The virtual network manager then uses the entity key to quickly determine an entity that comprises the component and updates a record of the entity in the entity inventory with the component's data.

Abstract: Communication between virtual and physical management tools can be hindered as new features or data are added to virtual network management tools which are incompatible with older versions of traditional network management software. To maintain compatibility with older software, a virtual network manager stores version compatibility numbers for data within an entity inventory. The entity inventory indicates active entities in a virtual network. When another management tool communicates with the virtual network manager, the management tool can register with a software version number or include a version number in a data request. The virtual network manager uses the version number to retrieve compatible data from the entity inventory and generate compatible entity models. The entity models may include more or less data and be formatted differently based on the version number received.

Abstract: A method of synthesizing color data through the use of what is called a Gradient Vector Synthesis method is comprised of calculating gradients at 0°, 45°, 90°, and 135° with respect to a generation point in a matrix of color data. A first-level edge test is performed by comparing each of the gradients to a noise threshold. If the first-level test indicates that an edge may be present along either of the diagonals, a second-level test may be performed. An interpolation technique is selected in response to the first-level edge test and, when performed, the second-level edge test. The selected interpolation technique is used to synthesize the missing color data at the generation point.
